  "message": "thinkpad-acpi: rework brightness support\n\nRefactor and redesign the brightness control backend...\n\nIn order to fix bugzilla #11750...\n\nAdd a new brightness control mode: support direct NVRAM checkpointing\nof the backlight level (i.e. store directly to NVRAM without the need\nfor UCMS calls), and use that together with the EC-based control.\nDisallow UCMS+EC, thus avoiding races with the SMM firmware.\n\nSwitch the models that define HBRV (EC Brightness Value) in the DSDT\nto the new mode.  These are: T40-T43, R50-R52, R50e, R51e, X31-X41.\n\nChange the default for all other IBM ThinkPads to UCMS-only.  The\nLenovo models already default to UCMS-only.\n\nReported-by: Alexey Fisher \u003cbug-track@fisher-privat.net\u003e\nSigned-off-by: Henrique de Moraes Holschuh \u003chmh@hmh.eng.br\u003e\nSigned-off-by: Len Brown \u003clen.brown@intel.com\u003e\n",
